Title: Data detection circuit for dynamic random-access memory
Inventor: DAISUKE KATOU
IPC: G11C11/4094
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To enhance the performance of a computer system by setting the resistance of a bit select means higher than the resistance of a row select means during data read interval thereby shortening the access and waiting time. SOLUTION: When a read access is started, ϕPRE lowers and quantized elements 210, 212 are turned off and thereby NFETs 214, 216, 218, 220 are turned off to disconnect a pair of bit lines BLL, BLL bar from VPRE. When a word line WLL is boosted, a call 160L is connected with the pair of bit lines and a pair of non-select bit lines are disconnected from a detection amplifier 166. When the amplifier 166 is set subsequently, a semimultiplexer 164L acts as a high load resistor on the amplifier 166 thus limiting the current. When a row switch 176 is selected, a majority of current is fed from an LOL having the semimultiplexer 164L to the amplifier 166. Consequently, the data can be detected substantially simultaneously and transferred on local data lines 182, 184.

IPC: G01F1/684
Filed: 1994-10-12
Abstract: PURPOSE: To prevent an engine trouble resulting from the separation of a resin plate by forming a projection in the resin plate and detecting from the appearance whether or not the resin plate is fused by ultrasonic waves to a resin body. CONSTITUTION: A resin body 1 of the air flowmeter consists of a main passage 3, a bypass passage 4, a circuit module 7, etc. A resin plate 2 and the body 1 are bonded by an ultrasonic fusing device to constitute the passage 4. At this time, a projection 5 is formed in the resin plate 2 to judge the ultrasonic fusion of the resin plate 2 from the appearance. After the fusing, the projection 5 is broken into such a size as to give no influences on characteristics and be detectable from the appearance. The shape of the projection is a semi-circle, a cylinder or the like. At least one or more projections are arranged (for instance, at four corners). When the projections 5 are formed in the resin plate 2 as above, it, can be detected from the appearance whether the resin plate 2 is fused to the body 1. Accordingly, arm engine trouble due to the separation of the resin plate 2 can be prevented.

Title: Word voice recognition equipment based on monosyllabic enunciation
Inventor: SEGAWA HIDEO
IPC: G10L15/04
Filed: 1987-09-30
Abstract: PURPOSE: To absorb failures of segmentation or syllabic sections to improve the word recognition rate by providing a word recognition part which recognizes words by DP(Dynamic programming) matching. CONSTITUTION: An acoustic processing part 2 outputs voice spectrum information to a single syllable recognition part 3 as acoustic information and outputs voice power information to a detection and segmentation part 4. This part 4 compares voice power information with one or plural prescribed threshold to detect the leading edge and the trailing edge of each syllabic section and segments acoustic features of individual syllabic sections. In the single syllable recognition part 3, a syllable dictionary 5 is used to recognize vowels in accordance with acoustic features, and syllables are recognized based on the result of this vowel recognition. When a syllabic category is identified, word recognition is next performed by DP matching.  Since detection errors of syllabic sections in the detection and segmentation part can be absorbed by DP matching, the word recognition rate is considerably improved.
